CARTON Filed Jan. 6, 1966 United States Patent 3,361,330 CARTON Edwin L. Arneson, Hackensack, NJ., assignor to Federal Paper Board Company, Inc., Bogota, N.J., a corporation of New York Filed Jan. 6, 1966, Ser. No. 519,038 2 Claims. (Cl. 229-39) ABSTRACT OF THE DISCLOSURE A carton formed from a blank of paperboard or like material for packaging fragile articles, such as radio tubes, which is in the form of a tube having four hingedly connected side walls with hinged flaps for closing the ends in which a flexible partition is formed by cutting the same from the material at one end of the blank so that it will swing inwardly of a line intermediate the side edges of the side wall which is taken from that end of the blank, with the free edge of the partition in sliding engagement with the adjoining side Wall which is taken from the other end of the blank, thereby enabling an article to be held in cushioned engagement between the partition and the two opposite side walls.

This invention relates to packaging and is more particularly concerned with improvements in a carton of a generally rectangular shape which is formed from a single blank of foldable sheet material and which is particularly adapted for enclosing relatively fragile articles so that they are cushioned therein for protection against damage.

It is a general object of the invention to provide a carton formed from a single blank of paperboard or other bendable sheet material which incorporates a partition structure affording protection and cushioned retention of an article within the carton so as to adapt the same for the packaging of articles of a fragile nature, such as, for example radio tubes.

It is a more specific object of the invention to provide an article enclosing carton of generally rectangular shape which is formed from a single blank of paperboard or similar foldable sheet material cut and scored so as to provide, when set up, a tubular body with a partition flap cut from a wall thereof and extending inwardly so that an article such as a radio tube may be nested between the partition and a pair of oppositely disposed walls of the carton.

These and other objects and advantages of the invention will be apparent from a consideration of the carton which is shown by way of illustration in the accompanying drawings wherein;

FIGURE 1 is a perspective view of a closed carton which embodies therein the principal features of the invention;

FIGURE 2 is a cross-sectional view taken on the line 2-2 of FIGURE 1, to an enlarged scale;

FIGURE 3 is a plan view of a blank cut and scored so as to form the carton of FIGURE 1;

FIGURE 4 is a perspective view of a carton illustrating a modified form thereof;

FIGURE 5 is a transverse section taken on the line 5-5 of FIGURE 4, to an enlarged scale; and

FIGURE 6 is a plan view of a portion of the blank which is cut and scored to form the carton of FIGURE 4.

Referring to the drawings, there is illustrated a carton 1i) (FIGURES 1 and 2) of rectangular shape which is provided with a partition 14 extending diagonally within the carton and adapted to retain therein an article which, for illustrative purposes, may be a radio tube T.

The carton lil is formed from a generally rectangular blank 12 which is cut and scored as illustrated in FIG- 3,351,339 Patented Jan. 2, 1968 URE 3. The blank 12 may be paperboard of suitable weight or other bendable sheet material. When out and scored or creased as shown, the blank 12 is divided by parallel transverse score lines 16, 18, 20 and 22 and parallel longitudinal score lines 24 and 26 into rectangular side wall panels 28, 30, 32, 34 and glue flap 36 with the side wall panels 28, 30 and 32 having integral end closing flaps 38, and 42 extending outwardly of the one longitudinal score line 24 and corresponding integral end flaps 38', 40' and 42' extending outwardly of the opposite score line 26. The blank is generally symmetrical about the longitudinal center line 11-11 and the end closure flaps are integrally hinged about the respective score lines 24 and 26 so that they are adapted to be folded for closing the ends of the tubular body formed when the side wall panels 28, 30, 32 and 34 are folded about the transverse score lines 16, 18, 24 and 22 and the glue flap 36 at one end of the blank is secured to the inside margin of the wall panel 28 at the other end of the blank. The center end flaps 46 and 40 are each provided with a narrow extension forming a tuck-in tab or flap 44 or 44'. A partition forming panel 14 is cut in the wall panel 34 and the glue flap 36 along the diagonal lines 46 and 46' which diverge in the direction inwardly of the end of the blank and terminate at opposite ends of the hinge forming score line 48, the latter extending transversely of the blank, parallel to and outwardly spaced relative to the corner forming score line 20. The partition panel has a dimension in the direction of the center line a-a which is greater than the distance between the transverse score lines 20 and 22 defining the side edges of the panel 34.

In forming the carton 10, the panels 34 and 28 are folded about the score lines 20 and 16, respectively, and the glue tab 36 is adhered by a suitable adhesive to the inside margin of the panel 28, leaving the portion of the partition forming panel 14 which underlies the panel 28 trapped between the adjoining wall panels 28 and 30 so that when the carton is opened up into tubular form the panel 14 will extend diagonally of the interior of the tubular body as shown in FIGURES 1 and 2 with the inner end thereof free for sliding engagement with the wall panel 28. Either end of the carton may then be closed by folding the flaps 38, 42 and 40 or 38, 42' and 40 in the order named into end wall formation with the tuck flap 44 or 44' being tucked inside of the margin of the panel 34. The tube T or other article may then be inserted through the open end of the carton so that it will be held by the partition 14 as indicated in FIGURE 2. The flexibility of the panel 14 will, of course, permit tubes of varying size to be accommodated in the carton, within limits.

In the modified form 50 of the carton which is illustrated in FIG'URES 4 to 6, blank 52 will be cut and scored in the same manner as the blank 12 except for the end portion thereof which is cut and scored as shown in FIGURE 6, so as to provide partition panels 54 and 55 within the area at the end of the blank bounded by the cutting lines 56, 57 and the hinge forming score lines 58 and 59. The score line 58 is parallel with the transverse score line 60 at the inner edge of the side wall panel 64, the latter corresponding to hinge line 20 and panel 34 of FIGURE 3. The hinge line 59 is angled 0ut wardly from the end of hinge line 58 and the smaller panel 55 is separated from the larger panel 54 by a cut slot 61. The smaller panel 55 has a score or perforated line 62 generally parallel with the hinge line 59 along which the panel may bend in use as shown in FIGURES 4 and 5. The partition panels 54 and 55 extend a predetermined distance beyond the free outer edge of the glue flap 66 the same as panel 14 in FIGURE 3, and have a dimension in that direction which is greater than the corresponding dimension of the side wall panel 64.

The blank 52 is set up into a tubular carton in the 'same manner as described with reference to the blank 7 panels. The partition panels 54 and 55 extend into the body of the set up carton for accommodating a tube T or other article having a base B or the like of larger diameter than the main body portion thereof as indicated in FIGURE so that the panels 54 and 55 constitute a holding means for retaining the tube in cushioned relation in thecarton. The panels 54 and 55 will, of course, bend or bow, within limits, to accommodate articles of varying size.

While particular materials and specific details of construction have been referred to in describing the forms of the carton illustrated, it will be understood that other suitable materials and difierent structural details may be resorted to within the spirit of the invention.
